My personal observation is that experimental physicists seem to be better (on average) at this than other disciplines.

Maybe something about having to deal with the physical world?

Experimental physics require large teams, thus communicators are more probable to be seen.

It depends... Dirac is a counterexample, while Bohr is a supporting example. It may just be that experimentalist who can explain their ideas with clarity and passion are the ones we notice first/most?

Dirac and Bohr were both theorists, not experimentalists! But you're right that it varies within disciplines.

I'm an experimental physics Ph.D. student working on LIGO, and I have also found that experimental physicists are often very good at motivating engineering from top to bottom. I think having depth of knowledge is part of it. My advisor has told me that some of the best experimentalists have sufficient depth of expertise to be theorists. I can't comment on how this compares to other fields (since I haven't worked outside of academia) but I have been very satisfied with how eloquent and deeply informed experimental physicists usually are.
